Systems and methods for improving quenched coke recovery
View Patent ↗The present technology is generally directed to systems and methods for improving quenched coke recovery. More specifically, some embodiments are directed to systems and methods utilizing one or more of a screen, barrier, or reflector panel to contain or redirect coke during or after quenching. In a particular embodiment, a quench car system for containing coke includes a quench car having a base, a plurality of sidewalls, and a top portion. The system can further include a permeable barrier covering at least a portion of the top of the quench car, wherein the permeable barrier has a plurality of apertures therethrough.
1. A coke quenching system, comprising:
a quench car having an open upper end portion and a plurality of sidewalls for containing coke; and
a quench tower configured to supply fluid for quenching coke, wherein the quench tower includes a deflection barrier having a free distal end portion that is positioned over the quench car, adjacent but in a spaced-apart relationship with the open upper end portion of the quench car, and having an opposing portion, opposite the free distal end portion, that is coupled directly to a wall of the quench tower, wherein the deflection barrier comprises a permeable barrier and is configured to deflect particulate coke that exits the quench car back into the quench car.
2. The coke quenching system of claim 1 wherein the quench tower includes a nozzle, and wherein the deflection barrier comprises an angled deflection plate coupled to or positioned below the nozzle.
3. The coke quenching system of claim 1 wherein the quench tower includes a plurality of nozzles directed toward the quench car, and wherein the deflection barrier is positioned above the nozzles.
4. The coke quenching system of claim 1 wherein the deflection barrier comprises a plurality of vertical draping barriers.
5. The coke quenching system of claim 1 wherein the deflection barrier comprises a movable barrier.
6. The coke quenching system of claim 1 , wherein deflection barrier comprises a plurality of confining plates.
7. The coke quenching system of claim 6 wherein the confining plates extend laterally inward toward an interior portion of the quench tower and are angled relative to a horizontal plane.
8. The coke quenching system of claim 1 wherein the quench tower includes a plurality of nozzles directed toward the quench car, and wherein the deflection barrier comprises a permeable barrier positioned at or below the nozzles.
9. The coke quenching system of claim 1 wherein the deflection barrier comprises a chain mesh.
